Fire and ice: huge blaze in Chicago warehouse

An ice-covered warehouse caught fire in Chicago on January 23. Fire department officials said it was the biggest fire the department had had to battle in years and one-third of all Chicago firefighters were on the scene at one point or another trying to put out the flames. An Arctic blast continues to grip the U.S. Midwest and Northeast, with at least three deaths linked to the frigid weather, and fierce winds made some locations feel as cold as minus 46 degrees Celsius.
